Engine/Transmission (1998.5 - 2002) ESN Number

[JTitone]

Hi. I'm trying to determine if the first 2 digits of the ESN number represent the block designation. My ESN starts with "56". Does this mean I have a 56 block and not a 53 block?

Look at the engine block driver side from underneath,if its a 53 you will see it there

If the truck gets close to 20 years of age then you don't have to worry about the 53 saga.

Hello Bob4X4 and Ozymandias. Thank you for your replies. The reason I asked the question was that I am selling my truck and the prospective buyer asked whether or not the truck had a 53 block. The weather here in NH has been just terrible with close to 100 inches of snow in 3 weeks and I just haven't been able to get under the truck to search for the block number. I thought by some chance if the ESN began with a 56 that it might indicate that the truck had a 56 block and I could relay this info back to the buyer.
